I have successfully used SQL Server/PostgreSQL/MongoDB Testcontainers in GitLab pipelines using exactly the same approach. But the Cosmos DB emulator wants to be special. This is the error it throws:
System.Net.Http.HttpRequestException : Connection refused (127.0.0.1:8081)
Why does it refuse the connection? What is necessary to get this running?

I don't know if you found a solution to you problem, but what you need to do is to configure
CosmosClientto useGatewaymode instead of the defaultDirectmode, Testcontainers Cosmos DB module needs this :
